power plant

Calon Energy has selected General Electric to upgrade the 800MW Sutton Bridge power plant in Lincolnshire, UK.

The upgrade is intended to increase the energy output of the natural gas-fired, combined-cycle facility by 3.4%, as well as lowering its start-up times and operating costs.

GE will be responsible for upgrading two existing GE 9FA gas turbines and a D-11 steam turbine at the plant. This will be achieved by equipping them with multiple applications from the OpFlex controls software suite, a Dry Low NOx 2.6+ combustor, and advanced gas path (AGP) technology solutions.

The upgrade package deployed at the plant will include OpFlex enhanced transient stability, AutoTune, variable load path, cold-day performance, extended turndown, variable inlet bleed heat, and variable airflow and steam turbine agility applications.

"Scope of work will cover installation of steam turbine thermal blankets for improving cold-start capability of the turbines."

GE expects to start on the upgrades in mid-2016, and it is likely to take several months to complete.

Calon Energy CEO Kevin McCullough said: "Along with other combined-cycle gas turbine plants in the UK, Sutton Bridge has competed with subsidised renewables, cheap coal and high gas prices."

GE has been responsible for the operation and maintenance (O&M) of the power station under a multiyear services agreement from 2013.
